Three different scale pictures (4:3, 16:9, 2.39: 1) in the film express his understanding of emotion and time. In my opinion, the feelings he wants to express are mainly concentrated in two aspects: on the one hand, exploring emotional freedom through personal choices under the tide of the times; On the one hand, he tortured the sadness of parting through his personal experience at that time.

Extended information 1999, Tao Er stood on the Fenyang Tower, looking at the county town that was advancing fiercely in the wave of reform, watching the bustling crowd and watching her heart drift away. She needs to make a choice, from two men who love her, choose one to join hands for life. One is a simple and dutiful Liang Zi, and the other is a straightforward Jinsheng. The former is not too sweet, and it is ordinary to manage miners' lamps and hats in coal mines;

The latter drove a coquettish red car and wore sunglasses, came back from doing business outside and bought a local coal mine, which was very imposing. In the face of love, the two seem to be equal and fair, but in reality, Jinsheng, who bought the coal mine, has already pulled the balance of competition to his side.

Taur told her father on the train that she was going to be with Zhang Jinsheng. Her father paused and seemed hesitant, but in the end he gave his daughter the right to choose and let her have the freedom to choose.

She chose Zhang Jinsheng, who can take her for a drive, take her to a disco and help her buy her favorite songs and CDs. She made the most important choice in her life quite freely, a choice that most people would agree with.

Max Zhang, who wears sunglasses to detonate explosives in the frozen river in winter, gets Taur. The problem of losing a job and a woman has nothing but an angry fist, so I have to silently take Taoer's wedding invitation, silently pack my bags and throw the keys to the roof.

This is the story in the first paragraph. Tao Er embraces the free choice of emotion, while Liang Zi shoulders the helpless reality of emotion. They took different roads and started the first separation.
